Enumerate all possible \(c\) and \(w\), and determine if a conforming pair \(c,w\) exists.

One can construct a string for \(c\) and \(w\) using a for statement and concatenation of strings. For more details, please refer to the sample code.

Sample code (C++):

#include <bits/stdc++.h>
using namespace std;

int main() {
    string s, t;
    cin >> s >> t;
    for (int w = 1; w < (int)s.size(); ++w) {
        for (int c = 0; c < w; ++c) {
            string now = "";
            for (int i = c; i < (int)s.size(); i += w) {
                now += s[i];
            }
            if (now == t) {
                cout << "Yes" << endl;
                return 0;
            }
        }
    }
    cout << "No" << endl;
}
